COMBINED CURBSTONE AND TELEGRApl-lwlRE CONDUIT.

SPECIFICATION forming part of Letters Patent No. 299,4:49, dated May 27, 1884.

Application filed December 18, 1883. (N0 model.)

To (1% whom it'mwy concern Be it known that I, JAMEs S. Woonwann,- a citizen of the United States, residing at the city and county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in a Combined Ourbstone and Telegraphire Conduit, of which the following is a full, clear, and exact description, referencebeinghad to the accompanying drawings, of which- Figure 1 is aperspective View, looking obliquely into one of the sections of which my combined curbstone and wire-conduit is composed, showing the wires in position, part of the lid or cover being broken away. Fig. 2 is a similar perspective View, partly in section, of the curb-conduit as in position in the street. Fig. 3 is a detail enlarged, beinga partial sectionof the conduit immediately in front of the wire-supporting posts or racks, showing the mode of securing the same. Fig. 4. is a horizontal section illustrating a means for securing together the conduit-sections in order to permit expansion and contraction thereof. Fig. 5 is a vertical section of the curb-conduit at a street-crossing. Fig. 6 is a plan view of the conduit at street-corners, one, a, being the usual rounded corner, and the other, I), being an inlet-corner.

This invention has relation to a combined curbstone and conduit for electrical purposes; and it consists in the construction and arrangeand particularly pointed out in the claims.

Referring to the annexed drawings, 0 marks of cast-iron or other suitable material, of any required dimensions, and shaped preferably as shown-that is to say, with the sides which extend above the level of the street-pavement, O, forming the curb, vertical, and those portions sunk in the ground, G, flaring outwardly, so as to insure against lateral or vertical displacement of the conduit, and to provide ample space in the lower part of the latter.

L' is the lid or cover, which is about flush of bolts 6, passing through holes therein, and through ledges Z on either side of section 0; or it may be hinged on one side, as seen in Fig. 2, and bolted on the other. A suitable water-tight packing, g-such as india-rubbe1' is introduced between the lid and the top of the ledges Z. The conductor-wires w are sustained in position by means of a series of vertical posts or racks, R, having upward projections These racks are located at requisite intervals apart, and their lower ends are inserted in sockets in the bottom of the conduit, while their upper ends are passed through corresponding holes in cross-stays D, whose extremities rest in opposite lugs or brackets, b, projecting a short distance from the sides of the conduit, as seen in Fig. 8. These crosspieces, as also the racks R, are made detach able. The ends of the conduit-sections G are provided with flanges f, having holes 7c,through which are passed bolts 6, for holding the same together. Suitable packing, g, is also inserted between the flanges before joining them together. When it is necessary or desirable to provide for longitudinal expansion and contraction of the several sections of the conduit, I make the same as shown in Fig. 4-that is, with overlapping ends-and secure them together and the interposed packing g by means of transverse bolts 6-, passing through longitudinal slots 1' in one of the flanges j. The conductor-wires w are inserted from the open top of the curb-conduit and rest in the teeth of rack R, as shown. The lid or cover is then bolted down. By this construction it is obvious that the wires are always easily accessible, and that the tearing up of the pavement in order to reach particular points, which is sometimes necessary with those conduits which are laid wholly under ground, is obviated, as all that is requisite in my invention is to open temporarily one of the cover or lid sections. \Vhen it is desired to conduct one or more wires into a building along the route of the conduit, I provide for that purpose at suitable intervals small latcral pipes P, Fig. 1, which are screwed or otherwise connected to the side of the conduit. v

The plans, Fig. 6, a and b, show my curbconduit at the corners of the street, a being rounded, as usual, b being an inward curve, on account of the inlet t.

The vertical sectional view, Fig. 5, represents my conduit at a point where it crosses the street where the curb ends, in which case the top is depressed, so that it is brought flush with the surface of the pavement at 0. Those of the conductor-wires which are above the line of the depressed or contracted part of the conduit are directed downward, and kept in proper position, in order to allow them to pass from the curb part to the contracted part, by means of transverse studs or posts .9, Fig. 5.

Having thus described my invention, I claim as new and wish to secure by Letters Patent- 1. A sectional conduit provided with openings or recesses in the floor thereof, and atransverse removable cross-bar provided with openings, in combination with rack-rods the ends of which are adapted to fit within the openings aforesaid, whereby the racks are main-
